Patients with bronchial asthma (BA) have evidence of increased vagal cholinergic tone. Although the cardiovascular-respiratory tests used in the past might have been biased by concomitant chest disease, coefficiencies of variance of the R wave to R wave (RR) interval (CVR-R) on electrocardiogram (ECG) have been applied to many diseases as a method of functional evaluation of the parasympathetic nerve system. In 24 hour recordings of ECG (Holter ECG), continuous values of CVR-R have been… CONTINUE READING
